汽轮机润滑油中添加剂对过滤性的影响

研究了添加剂X、Y对8种基础油过滤性的影响，添加剂中各单剂、助溶剂含量对基础油湿法过滤性的影响，湿法过滤性与乳液平均粒径之间的关系。结果表明：加入添加剂后，8种基础油的干法过滤性都略有下降，湿法过滤性则出现较大幅度的下降；使得基础油湿法过滤性变差的主要成分是添加剂中的助溶剂四乙二醇单甲醚；加入添加剂后，基础油形成的乳液的平均粒径越大，其湿法过滤性越差；醚类助溶剂的含量越高，湿法过滤性越差

INFLUENCE OF ADDITIVES ON FILTERABILITY OF TURBINE OIL

The influence of additives X and Y on the filter property of 8 kinds of base oils, the influence of the content of each single agent and cosolvent in additives on the wet filter properties of base oils, and the relationship between wet filter properties and average particle size of emulsion were studied. The results showed that the dry filter properties of the 8 base oils decreased slightly, while the wet filter decreased significantly. The main component that makes the wet filter property of base oil process worse was the cosolvent of additive, tetraethylene glycol monomethyl ether. After adding additives, the bigger the average particle size of the emulsion formed by the base oil, the worse its wet filtering property. The higher the content of ether cosolvent, the worse the wet filter properties.
